At the Optinet China Conference 2023, Wei Leping, the director of the Technology Committee of China Telecom Group, delivered a keynote speech entitled "The T-bit Era is Beginning".
Wei Leping believes that the demand for business broadband is almost endless, driving the evolution of optical networks towards the T-bit era. Currently, the DSP and optical modules of the T-bit era are basically mature, and transmission system experiments are also underway. The main bottleneck lies in the high cost of optical devices, which can be called the "bottleneck of the bottlenecks" of optical communication.
